MACHINE FOR MAKING CONCRETE BUILDINGS.

Specification of Letters Patent.

Application filed March 8, 1906. Serial N0. 304 ,826.

To all whom it may concern}:

Be it known that I, ALVA S. Mnnnm'r'r, a citizen of the United States, residin at Kansas City, in the county of Wyan otte and State of Kansas, have invented certain new End useful Improvements in Machines for Ma king Concrete Buildings; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to. nake and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

My present invention relates to anapparatus for constructing concrete buildings, and has for its object to provide an apparatus of the class described which is simple and economical in construction and operation and embodies the improved details of structure which will presently be fully described and pointed out in the claims, reference being had to the accompanying drawin s forming pait of this specification, in whic like reference numerals refer to like parts throughout the several views, and in which,

portion of previ- At each end of every moldplate is a lug bars 2627 which fit over the sides of said plates and have the outwardly projectmg flanges 28 which are engaged by the lugs 25, or a suitable latch, and are provided with shoulders 29 projecting from their inner surfaces to rest on the top. of the mold plates'and support said bars in a uniform position.

Bar 26 is provided at its upper end with the inwardly projecting channeled arm 30, and the horizontal arm 31 of arm 27 is of a width to fit within said channel where it is locked by the pin 32, (Fig. 7 which projects through registering perforations in arms 30 an 3],.

While ordinary finger lugs on the mold plates may serve to engage the brace bar arms, I prefer to provide said plates with the latches 33, which are loosely mounted in brackets 34 on the mold plates; each of said latches having a tooth 35 at each of its ends, the outer tooth being adapted to turn inwardly over the flange 28 of the brace bar and hold the latter rigidly in position. The brace bars may be placed in position from the sides and latched without the necessity of pushing them down from the top between the lugs and the plate, and are'cspeeially inc I the stay plate, which is wedge shaped as in-- adaptable for constructin walls with a reinforcement of wire net. 11 the large end of dicated in.Fig. 12, is an oblong erforation through which the lower end 0 the outer brace bar extends and 36 is a Wedge shaped pin adapted to fit within the perforation for the purpose of binding the stay plate and brace bar firmly together. wardly from the lesser end of the stay plate is a series of round perforations adapted to receive an anchoring pin when the brace bars have been removed. On pin 36 is a round shank 37 which .acts as an anchor for the inner mold plate and as a hinge pin. for the mold plates under circumstances which will presently be described.

Between the mold plates are inserted core boxes 38 for forming the hollow in the wall,

said boxes being made collapsible in order that they may be removed-when the wall is formed. I have found thatthe best manner of formin such collapsible boxes is to provide a bac plate 39 to which are hinged the movable members 40 and 41, each of which projects longitudinally a short distance and is then curved to form the box ends, and then backwardly to form the front boxmembers, the front edge of the member 41 overlapping the front edge of member 40. At the top and bottom of the overlapped edge of member 40 is an inwardly projecting lug 452 to which is pivoted the gate 43, the free end of which is adapted to impinge against the inner surface of the back of the core box, and retain the box rigidly opened. On ate 43 are the fingers 44, which are adapts to project through slotsin box member 40 and engage the loose end of member4l in order to bind the edges of the box firmly'together to prevent the cement or building material from flowing into the box; such constructlon allowing the box to be collapsed within the core which'it forms when the material has hardened, and to be easily removed.

On the end portion of the box are the arms 45, the arms on each box projecting far enough to contact with the arm projecting from an adjacent core box, said arms being alternately smooth and channeled in order that they may mesh and be fastened to-' gether. On each brace bar.v is pivoted a keeper 46 having a finger 46 adapted to fit over said projecting core box arms for the purpose of retaining the core boxes in aline v ment. I prefer to provide a cover for the core boxes and provide saidcovers 47 with end slots 48, adapted to receive the vertical core plates 49, said plates being preferably formed of'a single piece of sheet metal, which rests at the bottom on the stay plates and impinges at its edges, against the main core boxes. With such an arrangement, a narrow passage is left between the cores formed by the main core boxes when said Extending in boxes and plates have been withdrawn and a cfintinuous hollow is formed around the wa I provide with each set of mold plates, a sufficient number of corner plates, to which are attached the hinge members 51 having slots'52 adapted to fit over the bolts 53, and having end socket 54 and 54; socket 54 being sllghtly offset to accommodate a similar mold shown in Fig. 18 which comprises abox'6l composed of a suitable-number of sections, each lateral section having at its. outer end a horizontal laterally projecting lip 57 havin r an upwardly extending flange 57', which ange is integral with the end flange 58 of the box section. The floor of the box extends backwardly a suitable distance and is provided with perforations 59 adapted to receive the anchor pins 37 which brace the back plate 60 of the box.

Supported on box 61 are the side frames 62 of the door or window, said frames carrying at their upper ends the cross braces 63,

each .of the braces on each frame overlap:

ping its mate and being oined by the bolt 64, when the desired a justment is had. Frames 62 are preferably formed in sections,

as indicated; each section having pivoted to one of its ends, a T socket 65, and the free end of each frame section having a perforation therein, adapted to receive a pin 66, which may extend through both flanges of the Ts'ocket and through the frame section;

the side flanges on the body of the socket fitting over the frame and the flanges of the T forming a seat for the cross brace 67 which fits within said seats on each side of the door, or Window opening. Fitting be- I tween said side frames and the body of the building are the jamb molds 68, which may be of any suitable attern. The body flange of e ch of said mo d sections has a finger or socket 69 adapted to fit between the lugs 70 -on the side frames in order to retain same in position, said finger or socket being adjustable, and preferably secured in the desired position on. the frame'by means of bolts. In forming such window and dpor openings the body wall may be built up nearer the opening on the inside than the outside, necessitating a larger inside mold plate, and in forming corner joints with walls of different thickness, pl pltes of different lengths are necessary. ile plates of various lengths may be provided, I have found it more advlsable to provide extra small plates for this purpose than to try to provide special plates for the work, and- -firmly hold the parts together, and further facilitate their handling.

When the parts are arranged for forming each tier of the wall I insert a thin core plate 74, the flange 74 of which fits against the main core box and the body of which extends forwardly against the mold plate; these core plates bein at regular intervals so that while the Wal s are settling, should they contract, they will pull apart at these broken joints, and not crack through the body of the stone sections.

In Fig. 10 I show a cement plug which I insert into the opening left by the removal of the stay plates, and in Fig. 19 is a hopper, the guides 75 of which rest on the edges of the mold plates and receive the building material. With this means the tendency of the material to run down the outside of the mold, should too great a quantity be inserted is obviated and the feeding of the material is facilitated.

76 are arms attached to the ends of guards 75, and having perforations in their overlapping ends through which the bolts 77 may be inserted to bmd the members together:

by adjustment of bolts 77, the ho per may be widened or narrowed as desire ()n the inside corner mold plates, I place lu s 78 havin central erforations throu h a a p a which may be inserted the hinge pins 79, as shown in Fig. 2, for the purpose of locking the inside plates of abutting corners of a mold tier.

In use, placed on a suitable foundation and oined in the manner indicated. The core boxes are placed in position within the mold and the adjoining boxes are connected through their arms, over which. the cross bar clamps are lowered. The building material is poured into themold around the core boxes and after it has become hardened, said core boxes are collapsed and left in the hole until another set of mold plates are placed in position for forming a succeeding tier, when said core boxes are raised and put in place for said next tier, in this way making it unnecessary to remove the boxes and insurthe first tier of mold sections areing their being, at hand when desired. When the material in the first tier has hardened sufiiciently, the cross bars are removed and a succeeding tier of mold sections placed thereon, the plates in the first tier being held in place by the angle pin 36 which is dropped into the perforations in the stay plate and impinges against the plates as shown in Fig. 1. In said second tier and in each succeeding tier the end of each mold is setin the center of a preceding block'section in order to provide lapped joints for said sections. and give stability to the wall. Each 'full length mold set is provided with two core boxes which are set inthe boxes in each tier being set immediately over the core left in a preceding tier, and in this way forming a continuous vertical hollow throughout the wall; and by means of the sheet metal core plates connectin the main core boxes, a passage is formed between each main core box and the one ad'- joining, thereby forming a continuous horizontal passage for the air, and a barrier for frost, and dampness. The core plates between the main core boxes are staggered as indicated in Fig. 4; in order thatthe strength may not be impaired and at the same time provide the continuous hollow desired; the plates on. an up er tier also being set over the solid portion of wall in a previous tier for a like purpose.

In forming the windows and doors, the mold shown in Fig. 18 is placed in positio a body frame set thereon, and the jamb pos adjusted with their cross braces set for-the proper width, and with the jamb mold lates set between said posts and the body .rame; the jamb posts being made in Sections in order that a desired height may be secured, and each jamb section being provided with a cross brace extending across to tlge corresponding section on the opposite am If so desired, the lower portion of the jambs may terial has hardened the molds be removed and placed to form an upper portion, or. the whole may be formed at once. After the jambs are formed, material is poured into the sill mold and the sill or step formed around the jambs in a manner readil parent; after the sill or step has bar \the mold may be drawn, leaving a hollow under said sill or step which may be filled if desired. This apparatus makes it possible to construct such sills or steps without cutting out the stone from each side of the opening as it is ordinarily necessary to do.
